She and Avenger set off to fight and win the Holy Grail War.
Meanwhile, Shirō Emiya lives a peaceful life with all his friends from the 5th Holy Grail War. After one of her experiments changes time and space, Rin Tōsaka leaves for the Mages' Association in England to fix things. The Servants sense a new danger while dark creatures appear soon afterward. Shirō, as a precaution, sets off to ensure nobody is in danger and instead finds himself frequently meeting a mysterious girl, Caren Ortensia.
Both Bazett and Shirō find themselves in time loop that lasts four days, beginning of the fourth day of the 5th Holy Grail War. Each time they die or survive four days, they always awake on the first day of the loop aware of what has happened to them since the first time loop began. Determined to end the loop, Bazett, Avenger, and Shirō fight to discover the truth behind what's causing the endless four days.

The year is 2016 a.d. Some time ago, humanity had escaped the path to peril. This tale takes place after that period. This is the tale of a hero once again~

From Beast's Lair:
Based on the Doujin Fighting game, Melty Blood, made by the Doujin group, Watanabe Seisakujyo (now known as French Bread). This story is one of two side-story sequels occurring approximately a year after the 'good-ending' story of Arcueid from the original Type-Moon game, Tsukihime.

One year has passed since the 'Serial Vampire Homicide case' was solved by the deaths of Nero (Nrvnqsr) Chaos and Roa/Shiki Tohno. But now the rumors of serial murders are happening again. And so, once again, Shiki Tohno patrols the city to find this phantom killer. On patrol he meets--and fights--a mysterious woman named Sion Eltnam Atlasia; member of the church group 'Alchemist of Atlas', who seek to cure vampirism. But to do so she needs data from Arcueid, the last True Ancestor, to help her in her research. But this won't be easy: Ciel is also patrolling the city looking for the rumored killer, while Akiha has been acting strangely the past few days. Also, Arcueid hasn't been seen for awhile--could she be the killer...?

To repair the singularity of the future, the main character, Ryuka Fujimaru, will shift again to lay down a tremendous battle. Kengoro Nishide of "Umehara FIGHTING GAMERS!" Breathes new life into "FGO"
